MicroBit Brained Robots

Posted by korn Sep 25, 2018
I made a few Microbit Robots for the local library coding class.This one was printed from scratch. we started with just rf remote control but I plan to add line following sensors. These two used commercially available chassis. They all use a homemade dual motor driver I had posted on Instructables years ago. I originally designed it for CNC use but it works better in a bot. I used old Toshiba 8080 H bridge drivers. The first controllers used the accelerometer for steering. ...
Among the BBC Micro:bit’s onboard sensors is an accelerometer. This can be used for a myriad of applications, but I will use it for the simplest of motion detection – a step-counter!   The idea is simple, it detects enough motion and considers it a step.   As soon as the system turns on, it will begin “sensing” steps. The current step count will display on the LED matrix screen. The BBC micro library provides functions to recognize various gestures. As I read ...
The BBC Micro:bit is small, different than other boards. But this board is packed with features. One, in particular, I use in this project is the onboard compass, aka a magnetometer. I wanted to use it as a metal detector!   The earth has a magnetic field that the Micro:bit can detect easily. My concept was to detect disruptions to the Earth’s magnetic field around the Micro:bit.   The magnetometer (compass) measures the magnetic field in 3D coordinates – x, y, z. When t ...
